Just got an iPad. When using USB cord to connect to computer, iPad charging indicator says "not charging". iTunes synchs fine. When I use wall outlet to charge all OK. Any ideas why not charging through ANY USB port on my laptop? Thank you,

MacBook, Mac OS X (10.5.7)

    It probably will be charging, just very slowly (and will show the Not Charging message) - USB ports tend not to provide enough power to make charging an iPad efficient. The best/quickest way to charge it is via the wall charger

    Leave it plugged in after you complete the sync, let it go to sleep (lock) and the charging rate will increase and you'll get a charging indication.

    The charger provided with your iPad can put out up to 2A of charging current. The best you're going to see from a USB port is somewhere around 500mA, that only from high-power ports and can be less depending on the computer. Seeing the "Not Charging" while syncing is perfectly normal.

    Likely, when connected to the computer, the iPad will not charge while using it.
    It may charge while it is not being used (turned off) and connected to the computer.

    I have never seen my iPad charge from my PC until the last time it was connected for a synch. It was at about 20% when I plugged in the USB. I forgot about it for at least 4 hours. I disconnected and was going to charge with the wall charger but noticed it said 100%. It just takes a long time to charge.

    The funniest part is if I use the same USB port on my MacBook Air booted in WIN 7 it says "not charging", but if I boot in Apple OS, then there seems to be no problem and the iPad seems to charge OK ... ???

    Even though the port is able to provide more power, the OS needs to know this in order to enable it.
